1. A gyratory crusher comprising:
a crushing head provided with a first crushing shell; a frame provided with a second crushing shell, wherein the first and second crushing shells between them define a crushing gap; an eccentric provided with a first envelope surface and a second envelope surface, the second envelope surface being eccentrically arranged relative to the first envelope surface; a third envelope surface extending about a central axis and having a longitudinal extension along said central axis, wherein the first envelope surface of the eccentric being journalled to the third envelope surface and arranged to rotate about said central axis, and the second envelope surface of the eccentric being journalled to the crushing head, whereby rotation of the eccentric will provide a gyratory movement to the crushing head; and a first slide bearing and a second slide bearing provided between the first and third envelope surfaces, wherein the first and second slide bearings are vertically separated from each other along said central axis a distance (VDi) such that a distance-to-height quotient (VDi/H1; VDi/H2) of the first or second slide bearing that has the greatest height (H1; H2) is greater than 0.8. |
